I have a nomad racing (BOV) £60. Nomad racing are an old skool cosworth tuning company and this dumpavalve is rare as f*ck it consists of billet construction and the piston is also made out of billet alloy unlike alot of cheapy ones which have a plastic piston and are prone to leaking, No leaks and works perfect, PM if your interested and il put up a for sale thread so u can buy with confidence! For the HDI intercooler you need a 32mm to 25mm reducer they cost about £5-£6 from anyone who supplies silcone hoses
